I know, I know. All 802.11b and 802.11g cards should work fine.. BUT! And this is a big but! I'm paranoid. This is due to the fact the internal a+b+g mini-PCI Module isn't picking up the base station's signal at all. I have a free PC card free and I'm thinking if I can get a new card maybe the compatibility issues will be resolved. So, has anyone tried networking PC labtops with Apple Base Stations much and found any paticular card/brand to be of note?
